A configuration consisting of a connecting part 1 and a pair of clamping connecting parts 2, a configuration consisting of a pair of ladder connecting parts 1 and one clamping connecting part 2, a configuration consisting of a configuration in which both the ladder connecting part 1 and the clamping connecting part 2 are composed of one. It can also be a configuration.

以下、本実施例に係る構成各部について詳細な説明をする。 Hereinafter, detailed explanation will be given of each component according to this embodiment.

梯子連結部１は、図１に図示したように適宜な金属製の部材から成る一対のコ字状半体１’，１”同士を連結して成る角筒状体であり、一方のコ字状半体１’に設けた止着部材１ａを他方のコ字状半体１”に設けた長孔１ｂにスライド自在に止着連結しており、周面の一部にはスライドにより開口度合いが可変する開口部１ｃを有し、この開口部１ｃを通過させて梯子50の縦材50ａに着脱自在に被嵌連結するように構成されている。 As shown in FIG. 1, the ladder connecting part 1 is a rectangular cylindrical body formed by connecting a pair of U-shaped halves 1' and 1'' made of appropriate metal members, and one of the U-shaped halves 1' and 1'' is connected to each other. A fastening member 1a provided on one half body 1' is slidably fixed and connected to a long hole 1b provided on the other U-shaped half body 1'', and a part of the circumference is slidably connected to the opening degree. It has an opening 1c which is variable, and is configured to be inserted through the opening 1c and connected to the vertical member 50a of the ladder 50 in a detachable manner.

従って、梯子連結部１は種々のサイズ（径）の縦材50ａに被嵌連結することができる。 Therefore, the ladder connecting portion 1 can be fitted and connected to the vertical members 50a of various sizes (diameters).

また、梯子連結部１は、後述する挟持連結部２と所定長さの紐状部材７（ワイヤー）を介して連設されている。尚、この紐状部材７の長さは、梯子50に載った作業者が軒先部60ａに挟持連結部２を挟持連結できる手が届く範囲の長さに設けられている。 Further, the ladder connecting portion 1 is connected to a clamping connecting portion 2, which will be described later, via a string-like member 7 (wire) having a predetermined length. The length of this string-like member 7 is set to a length within which a worker standing on the ladder 50 can reach and connect the clamping connection part 2 to the eaves edge part 60a.

挟持連結部２は、図１～３に図示したように適宜な金属製の部材で形成したものであり、板状の第一挟持部２ａを有する本体部２’と、この第一挟持部２ａの下方対向位置に設けられる板状の第二挟持部２ｂを有し、本体部２’に対して昇降機構８を介して昇降自在に設けられる可動部２”と、この第一挟持部２ａ及び第二挟持部２ｂのクランプ状態とアンクランプ状態を操作する操作部３とで構成されており、第一挟持部２ａと第二挟持部２ｂの間隔は軒先部60ａよりも広い間隔に設定されている。 As shown in FIGS. 1 to 3, the clamping connection part 2 is formed of an appropriate metal member, and includes a main body part 2' having a plate-shaped first clamping part 2a, and a main body part 2' having a plate-shaped first clamping part 2a. It has a plate-shaped second clamping part 2b provided at a position facing downward from the main body part 2', and is provided with a movable part 2'' that can be freely raised and lowered via a lifting mechanism 8, and this first clamping part 2a and It is composed of an operation part 3 that operates the clamped state and unclamped state of the second clamping part 2b, and the interval between the first clamping part 2a and the second clamping part 2b is set to be wider than the eaves part 60a. There is.

具体的には、昇降機構８は、可動部２”の上部に設けられ本体部２’の上部を貫通する可動軸８ａに枢着される偏心カム部８ｂを有する操作部３（回動レバー３’）と、本体部２’の上部に設けられ操作部３の偏心カム部８ｂを受けるカム受け部８ｃとで構成されており、操作部３の起伏回動に伴い可動部２”が昇降することで、第一挟持部２ａに対して第二挟持部２ｂが接離移動するように設けられている（図２，３参照）。符号８ｄは第二挟持部２ｂを常時開放方向へ付勢する付勢部材（コイルばね）である。 Specifically, the elevating mechanism 8 includes an operating section 3 (rotating lever 3 ') and a cam receiving part 8c which is provided on the upper part of the main body part 2' and receives the eccentric cam part 8b of the operating part 3, and the movable part 2'' moves up and down as the operating part 3 moves up and down. Thus, the second clamping part 2b is provided so as to move toward and away from the first clamping part 2a (see FIGS. 2 and 3). Reference numeral 8d denotes a biasing member (coil spring) that always biases the second clamping portion 2b in the opening direction.

従って、操作部３を起伏回動させることでクランプ状態とアンクランプ状態との切り替え操作（挟持操作及び解除操作）が行える。 Therefore, by rotating the operating portion 3 up and down, switching operations between the clamped state and the unclamped state (clamping operation and release operation) can be performed.

また、この操作部３の先端部（レバー先端部）には引動することで解除操作を可能にする引動線材４が延設されている。 Further, a moving wire 4 is extended from the tip end of the operating portion 3 (lever tip portion), which enables a release operation by being pulled.

この引動線材４は、図１～３に図示したように適宜な合成樹脂製の紐部材であり、その長さは、梯子50を設置した箇所（例えば地上）において作業者が手にすることができる長さに設定されている。 As shown in FIGS. 1 to 3, this pulling line 4 is a string member made of a suitable synthetic resin, and its length is such that it can be easily grasped by the worker at the location where the ladder 50 is installed (for example, on the ground). The length is set as long as possible.

従って、梯子50から降りた箇所（例えば地上）で引動線材４を引動して操作部３を解除操作することができる。 Therefore, the operating portion 3 can be released by pulling the moving wire 4 at a place where the user descends from the ladder 50 (for example, on the ground).

また、本体部２’の後方部位にして引動線材４の引動方向における操作部３の対向位置には該引動線材４を垂れ下がり支持する滑車部５が設けられている。 Further, a pulley portion 5 that hangs down and supports the pulling wire 4 is provided at a rear portion of the main body portion 2' and facing the operating portion 3 in the pulling direction of the pulling wire 4.

具体的には、滑車部５は、図１～３に図示したように本体部２’の後方部位に突設される筒状部２ｃにスライド体５ｂを上下方向にスライド自在に設け、このスライド体５ｂの上端部に滑車５ａを設けて構成されており、滑車部５は、挟持連結部２に対して接離自在、即ち、屋根60の軒先部60ａに挟持連結部２を挟持連結した状態において、屋根60の屋根面に対して任意の距離に調整できるように設けられている。 Specifically, as shown in FIGS. 1 to 3, the pulley portion 5 includes a slide body 5b provided on a cylindrical portion 2c protruding from the rear portion of the main body portion 2' so as to be slidable in the vertical direction. A pulley 5a is provided at the upper end of the body 5b, and the pulley part 5 can move toward and away from the clamping connection part 2, that is, in a state in which the clamping connection part 2 is clamped and connected to the eave part 60a of the roof 60. , it is provided so that it can be adjusted to any distance with respect to the roof surface of the roof 60.

具体的には、本来、操作部３を小さな力で操作するためには滑車部５（滑車ａ）を挟持連結部２から離れた位置（高い位置）にするのが良いが、屋根勾配が急な場合には、挟持する部位と滑車部５（滑車ａ）の距離が離れていると、挟持する部位（軒先部60ａ）に強い負荷が掛かって破損する恐れがあるため、操作部３の解除操作の支障とならない程度に滑車部５（滑車ａ）を低い位置に調整することで、挟持する部位（軒先部60ａ）の破損を防止することができる。 Specifically, in order to operate the operation part 3 with a small force, it is better to place the pulley part 5 (pulley a) at a position away from the clamping connection part 2 (in a high position), but if the roof slope is steep, In such a case, if the distance between the part to be clamped and the pulley part 5 (pulley a) is large, the part to be clamped (the eaves part 60a) may be subject to a strong load and be damaged, so do not release the operating part 3. By adjusting the pulley portion 5 (pulley a) to a low position to the extent that it does not interfere with operation, damage to the portion to be held (the eaves portion 60a) can be prevented.

従って、屋根勾配に応じて滑車部５（滑車ａ）の高さ位置を、挟持する部位（軒先部60ａ）の破損を防止しつつ、使い勝手の良い位置に調整することができる。 Therefore, the height position of the pulley part 5 (pulley a) can be adjusted to a convenient position according to the roof slope while preventing damage to the part to be held (the eaves part 60a).

また、本体部２’には、滑車部５で支持されて垂れ下がる引動線材４の垂れ下がり部位を通過させて該引動線材４の引動方向をガイドするガイド部６が設けられている。 Further, the main body portion 2' is provided with a guide portion 6 that guides the drawing direction of the drawing wire 4 by passing through a hanging portion of the drawing wire 4 that is supported by the pulley portion 5 and hanging down.

このガイド部６は、本体部２’の背面側下方位置に断面円形の環状部材を設けて構成されており、引動線材４を常に引動し易い状態が得られることになり、しかも、引動線材４が滑車部５から外れるなどの不具合の発生を防止することもできる。 This guide part 6 is configured by providing an annular member with a circular cross section at a lower position on the back side of the main body part 2', and a state in which the drawing wire 4 can be easily pulled at all times can be obtained.Moreover, the drawing wire 4 It is also possible to prevent problems such as the pulley part 5 coming off the pulley part 5.

本実施例は上述のように構成されているから、梯子50に梯子連結部１を連結すると共に、屋根60の軒先部60ａに挟持連結部２を挟持連結することで、梯子50を屋根60に固定することができる。必要に応じて滑車部５の位置を調整する。尚、本実施例では軒先部60ａとして唐草を対象としているが、本実施例の特性を発揮する構成であれば適宜採用し得るものである。 Since the present embodiment is configured as described above, the ladder 50 is connected to the roof 60 by connecting the ladder connecting part 1 to the ladder 50 and connecting the clamping connecting part 2 to the eaves part 60a of the roof 60. Can be fixed. Adjust the position of the pulley portion 5 as necessary. In this embodiment, an arabesque is used as the eaves part 60a, but any structure that exhibits the characteristics of this embodiment may be adopted as appropriate.

この屋根60への固定（挟持連結部２の挟持連結）を解除する場合には、操作部３の引動線材４を引動すると、屋根60の軒先部60ａに対する挟持連結部２の挟持連結が解除される。つまり、梯子50から降りた地上において屋根60の軒先部60ａに対する挟持連結部２の挟持連結を解除することができる。 In order to release the fixation to the roof 60 (the clamping connection of the clamping coupling part 2), by pulling the pulling wire 4 of the operating part 3, the clamping connection of the clamping coupling part 2 to the eaves part 60a of the roof 60 is released. Ru. That is, on the ground after descending from the ladder 50, the clamping connection of the clamping connection part 2 to the eaves portion 60a of the roof 60 can be released.

よって、本実施例によれば、屋根60からの挟持連結部２の取り外し作業を安全に行うことができる。 Therefore, according to this embodiment, the work of removing the clamping connection part 2 from the roof 60 can be performed safely.

また、本実施例は、梯子連結部１は、左右の縦材50ａ夫々と連結する一対の梯子連結部１で構成されているから、屋根60の軒先部60ａに対する良好な固定状態が得られる。 Further, in this embodiment, since the ladder connecting portion 1 is constituted by a pair of ladder connecting portions 1 that are connected to the left and right vertical members 50a, a good fixing state to the eaves portion 60a of the roof 60 can be obtained.

また、本実施例は、挟持連結部２は、屋根60の軒先部60ａに梯子50を間にして所定間隔で挟持連結する一対の挟持連結部２で構成されているから、この点においても屋根60の軒先部60ａに対する良好な固定状態が得られる。 Further, in this embodiment, the clamping connecting parts 2 are constituted by a pair of clamping connecting parts 2 that are clamped and connected to the eave part 60a of the roof 60 at a predetermined interval with the ladder 50 in between.
